@POST在 RESTful Web 服务中

2022-09-01 10:44:28

我一直试图使用泽西岛了解RESTful网络服务中的@POST。我已经经历了 http://www.vogella.com/articles/REST/article.html,并且能够获得有关@POST一些信息,但感到困惑和混乱。任何人都可以用一个简单的例子来解释@POST,或者分享关于相同的链接。

通过上面的链接中的TODO对象实现@POST很好,但我希望通过其他一些简单的示例来学习@POST,以便我可以继续开发自己的复杂@POST示例。

帮助将是可观的,谢谢。

请在下面找到示例,它可能会对您有所帮助

package jersey.rest.test;

import javax.ws.rs.DELETE;
import javax.ws.rs.GET;
import javax.ws.rs.HEAD;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;

@Path("/hello")
public class SimpleService {
    @GET
    @Path("/{param}")
    public Response getMsg(@PathParam("param") String msg) {
        String output = "Get:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @POST
    @Path("/{param}")
    public Response postMsg(@PathParam("param") String msg) {
        String output = "POST:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @POST
    @Path("/post")
    //@Consumes(MediaType.TEXT_XML)
    public Response postStrMsg( String msg) {
        String output = "POST:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @PUT
    @Path("/{param}")
    public Response putMsg(@PathParam("param") String msg) {
        String output = "PUT: Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @DELETE
    @Path("/{param}")
    public Response deleteMsg(@PathParam("param") String msg) {
        String output = "DELETE:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @HEAD
    @Path("/{param}")
    public Response headMsg(@PathParam("param") String msg) {
        String output = "HEAD:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }
}

对于测试,您可以使用任何工具,如RestClient(http://code.google.com/p/rest-client/)

REST Webservice: (http://localhost:8080/your-app/rest/data/post)

package com.yourorg.rest;

import javax.ws.rs.Consumes;
import javax.ws.rs.POST; 
import javax.ws.rs.Path; 
import javax.ws.rs.Produces; 
import javax.ws.rs.core.MediaType; 
import javax.ws.rs.core.Response;

    @Path("/data")
public class JSONService {

    @POST
    @Path("/post")
    @Consumes(MediaType.APPLICATION_JSON)
    public Response createDataInJSON(String data) { 

        String result = "Data post: "+data;

        return Response.status(201).entity(result).build(); 
    }

客户发帖子:

package com.yourorg.client;

import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;

public class JerseyClientPost {

  public static void main(String[] args) {

    try {

        Client client = Client.create();

        WebResource webResource = client.resource("http://localhost:8080/your-app/rest/data/post");

        String input = "{\"message\":\"Hello\"}";

        ClientResponse response = webResource.type("application/json")
           .post(ClientResponse.class, input);

        if (response.getStatus() != 201) {
            throw new RuntimeException("Failed : HTTP error code : "
                 + response.getStatus());
        }

        System.out.println("Output from Server .... \n");
        String output = response.getEntity(String.class);
        System.out.println(output);

      } catch (Exception e) {

        e.printStackTrace();

      }

    }
}
